Self-taught chemistry…test?

I’ve been teaching myself chemistry with a textbook and chat gpt, basic college chemistry, and I was wondering if anyone knows of a site, or book, I can use/buy to test myself as if it was a midterm or final.

I want to test to get the credit at school, without having to pay for the whole class, (taking the full class won’t be an option financially or time wise).

Long story short: can’t take a regular class, want to take test to see if all the self teaching is equivalent.
